We look at the division of 262321 by 91 
The aim is to understand the frequency of 91 in 262321.

Going ahead to step 1:
91 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 91

Step 2:
26 divided by 91 is 0 with a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Bring next digit (2) of the dividend behind the 26 and repeat the process: 262 / 91

Going ahead to step 3:
If we divide 262 by 91, we get 2 and a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 182 from 262 leaves us with 80.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 91

Going ahead to step 4:
91 can be fit into 803 8 times, resulting in a remainder of 75.
The next digit of our result is 8. 
Result so far: 28.0
If we subtract 728 from 803, we get 75.
Take the next digit (2) from the dividend and append it to 75, then repeat: 752 / 91

Let's proceed to step 5:
91 can be fit into 752 8 times, resulting in a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 288.0
Deduct 728 from 752 and we're left with 24.
Include the next digit (1) from the dividend after 24, then repeat: 241 / 91

Advancing to step 6:
The number 91 fits into 241 2 times, leaving a remainder of 59.
Use 2 as the next digit of our solution. 
Result so far: 2882.0
Subtracting 182 from 241 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 7:
When dividing 590 by 91, we get 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 2882.6
If we subtract 546 from 590, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 8:
When dividing 440 by 91, we get 4 with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 2882.64
The remainder is 76 after subtracting 364 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 9:
760 divided by 91 is 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 2882.648
Subtract 728 from 760 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
91 can be fit into 320 3 times, resulting in a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 2882.6483
The remainder is 47 after subtracting 273 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 11:
91 can be fit into 470 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 2882.64835
Deduct 455 from 470 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
150 divided by 91 is 1 with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 2882.648351
Subtracting 91 from 150 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 13:
590 divided by 91 is 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 2882.6483516
If we take 546 away from 590, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
If we divide 440 by 91, we get 4 and a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 2882.64835164
Deduct 364 from 440 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

In conclusion, the division gives 2882.64835164 with a balance of 7.6e-08.
